Kireni wapamtunda wamitundu iwiri wokhoza kunyamula zinthu zolemera zosiyanasiyana

Zigawo ndi Mfundo Yogwirira Ntchito ya Crane Imodzi Yokwera Pamwamba:

1. Single Girder: Kapangidwe kake ka girder overhead crane ndi mtengo umodzi womwe umadutsa malo ogwirira ntchito. Nthawi zambiri amapangidwa ndi chitsulo ndipo amapereka chithandizo komanso njira yoti zigawo za crane ziziyenda.
2. Hoist: Chokwezera ndi gawo lokweza la crane. Zimapangidwa ndi injini, ng'oma kapena pulley system, ndi mbedza kapena cholumikizira. The hoist ndi udindo kukweza ndi kutsitsa katundu.
3. Magalimoto Omaliza: Magalimoto omalizira amakhala mbali zonse za girder imodzi ndikuyika mawilo kapena zodzigudubuza zomwe zimalola crane kuyenda panjira. Iwo ali okonzeka ndi galimoto ndi galimoto limagwirira kupereka yopingasa kayendedwe.
4. Bridge Drive System: Njira yoyendetsera mlatho imakhala ndi mota, magiya, ndi mawilo kapena zodzigudubuza zomwe zimathandiza kuti crane iyende kutalika kwa girder imodzi. Amapereka kayendedwe kopingasa kwa crane.
5. Kuwongolera: Crane imayendetsedwa ndi gulu lowongolera kapena pendant control. Zowongolera izi zimalola woyendetsa galimotoyo kuyendetsa galimotoyo, kuwongolera kukweza ndi kutsitsa katundu, ndikusuntha crane munjira yowuluka.

Mfundo Yogwirira Ntchito:

Mfundo yogwirira ntchito ya crane ya girder pamwamba ili ndi izi:

1. Yatsani Mphamvu: Kireni imayatsidwa, ndipo zowongolera zimayatsidwa.
2. Kukweza Ntchito: Wogwiritsa ntchito amagwiritsa ntchito zowongolera kuti ayambitse injini yokweza, yomwe imayambira njira yokweza. Chingwe kapena chonyamulira chimatsitsidwa pamalo omwe mukufuna, ndipo katunduyo amamangiriridwa pamenepo.
3. Movement Horizontal: Woyendetsa amatsegula makina oyendetsa mlatho, omwe amalola kuti crane isunthike molunjika pagulu limodzi kupita kumalo omwe akufunidwa pamwamba pa malo ogwira ntchito.
4. Vertical Movement: Woyendetsa amagwiritsa ntchito zowongolera kuti ayambitse injini yokweza, yomwe imakweza katunduyo molunjika. Katunduyo amatha kusunthira mmwamba kapena pansi ngati pakufunika.
5. Kuyenda Mwamng'ono: Katunduyo akadzakwezedwa, woyendetsa atha kugwiritsa ntchito zowongolera kuti asunthire crane mopingasa m'mbali mwa girder imodzi kupita pamalo omwe akufuna kuti ayike katunduyo.
6. Ntchito Yotsitsa: Wogwiritsa ntchitoyo amayendetsa galimoto yokwezera motsitsa, pang'onopang'ono kutsitsa katunduyo pamalo omwe akufuna.
7. Kuyimitsa Mphamvu: Ntchito yokweza ndi kuyika ikamalizidwa, crane imazimitsidwa, ndipo zowongolera zimazimitsidwa.

Ndikofunika kuzindikira kuti zigawo zenizeni ndi mfundo zogwirira ntchito zingasiyane malinga ndi mapangidwe ndi kupanga crane imodzi ya girder.

1. Kuchita Bwino Kwam'mlengalenga: Single girder overhead cranes amadziwika ndi mapangidwe awo opulumutsa malo. Ndi mtengo umodzi womwe umadutsa malo ogwirira ntchito, amafunikira chilolezo chocheperako poyerekeza ndi ma cranes awiri, kuwapangitsa kukhala oyenera malo okhala ndi mutu wocheperako.
2. Zotsika mtengo: Ma Crane a Single girder nthawi zambiri amakhala otsika mtengo kuposa ma cranes a double girder. Mapangidwe awo osavuta komanso zigawo zochepa zimapangitsa kuti pakhale ndalama zochepa zopangira ndi kukhazikitsa.
3. Kulemera Kwambiri: Chifukwa cha kugwiritsa ntchito mtengo umodzi, ma cranes a single girder ndi opepuka poyerekezera ndi ma cranes awiri. Izi zimapangitsa kuti zikhale zosavuta kuziyika, kuzisamalira, komanso kugwira ntchito.
4. Kusinthasintha: Single girder cranes amatha kusinthidwa kuti akwaniritse zofunikira zosiyanasiyana zokweza. Amapezeka m'masinthidwe osiyanasiyana, mphamvu zonyamulira, ndi ma spans, zomwe zimawalola kuti azisinthidwa kumalo osiyanasiyana ogwira ntchito komanso kukula kwake.
5. Kusinthasintha: Ma cranes awa amapereka kusinthasintha poyenda. Amatha kuyenda utali wa chotchinga chimodzi, ndipo chokwezacho chimatha kukweza ndi kutsitsa akatundu ngati pakufunika. Izi zimawapangitsa kukhala oyenera ntchito zosiyanasiyana, kuchokera ku zopepuka mpaka zapakatikati zokweza ntchito.
6. Kukonza Kosavuta: Ma Crane a Single girder ali ndi mawonekedwe osavuta, omwe amapangitsa kukonza ndi kukonza kukhala kosavuta poyerekeza ndi ma cranes apawiri. Kupeza zigawo zikuluzikulu ndi malo oyendera ndizosavuta, kuchepetsa nthawi yopuma panthawi yokonza.
